For reducing a present during the period of the maize threshes, the intensity of labour, raises working efficiency, design maize sheller. Maize sheller used to the dry corn after on threshing. Be machine's turn to have mainly enter except that mouth, bars form notch and nail tooth the cylinder threshing and ponent etc. posed of. Take electric motor as driving force source, driving force exports axis output from the electric motor, the nail tooth seed-husking cylinder threshes on the cylinder threshing again by the fact that belt delivery arrives at the nail tooth, coordinating bars form notch board with the maize, beside plies with bars form notch board separation and the outside discharging airfram, but the maize core discharges airframe from another one end entering material.
